Had a Dell AW3821DW and thought to myself, I could still use more screen real estate for my overall productivity workflow. I switch back and forth all day between my PC for personal use and a M4 Macbook for work. This led me to researching and upgrading from the 3840x1600 Dell to the 5120x2160 Lenovo. Immediately, I can see the benefit of the new monitor on my Windows PC, even at 125% scaling. However, this morning I used it with my Macbook for the first time and what a mess it is trying to deal with the scaling: either it's the full screen resolution but much of the UI elements are too small and can't be scaled up at all, or I'm scaling up everything universally to the "in-between" setting and it's less resolution than I had with the 1440p monitor. The screen mirroring is also now problematic: forget trying to read anything on the Macbook's screen when I'm using the monitor for the PC input. And, just for kicks, I'm maxed out at 30hz refresh rate, which is evidently an HDMI cable restriction?
I'm going to have to try to sort some of this out on my own but it was not such an ecouraging experience on the first try, that's for sure. I was probably less productive trying to fuss with everything than if I had just stuck with the 1440p monitor. Any obvious tips from those here more experienced with Mac's and ultrawides that could help a brother out? Feedback much appreciated and thank you!
